ADELBERT S. JAQUITH, 0F BOSTON, MASSACHUSETTS, ASSIGNOR TO MATTHEW H.SWIFT, OF HARTFORD, CONNECTICUT.

AUTOMATIC SELF-DRIVEN FILLET-MACHINE FOR APPLYING METALLIC LEAF.

Application led March'lS, 1915.

To all ywhom it may concern.'

Be it known that I, ADELBERT S. JAQUITH, a citizen cf the United States,and resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inAutomatic Self-Driven Fillet-Machines for Applying Metallic Leaf, ofwhich the following is a specification.

This invention relates to machines for transferring from a package rollto a fillet roll, a fillet of metallic leaf, such as gold, silver. etc.,the fillet adhering to the fillet roll and being transferable thereby toa surface to be ornamented.

The invention is embodied in a machine in which the portion of thefillet passing to the fillet roll is supported by and moves on a feedingmember such as a rotary drum, until it is taken up by the fillet roll,the feeding member being yieldingly supported in a given normal positionand shiftable therefrom by pressure of the fillet roll on the feedingmember, such depression causing a fillet-feeding movement to be impartedto the feeding member by a suitable power mechanism or motor, theorganization being such that the feeding movement of the feeding memberis automatically stopped when the fillet roll is removed and the feedingmember returns automatically to its normal position.

The invention is also embodied in various improvements relating to themeans for rotatably confining the package roll under tension, to meansfor feeding from the machine the paper strip which separates theconvolutions of the fillet. and to other' parts of the machine.

Of the accompanying drawings forming a part of this specification:Figure 1 represents a top plan view of a machine embodying my invention,the cover hereinafter referred to being removed: Fig. 2 represents asection on line 2 2 of Fig. 1, showing the cover in place: Fi g. 3represents a section on line 3*?) of Fig. 1: Fig. 4 represents a sectionon line 4 4 of Fig. 1; Fig. 5 represents a section on line 5 5 of Fig.1; Fig. 6 represents a section on line 6 6 of Fig. 1: Fig. T representsa section on line 7 7 of Fig. 1; Fig. 8 represents a side view of aaortion of the drum and the fillet roll applie thereto; Fig. 9represents a side elevation of the Specification of Letters Patent.

machine, the cover being shown in section; Figs. 10, 11, 12 and 13represent fragmentary views illustrating the means for supporting thepressure roll hereinafter described.

The same reference characters indicate the same or similar parts in allthe views.

The machine of my invention includes a motor which is preferably springdriven. To illustrate the invention I have shown a spring motor of thetype employed to drive the record cylinder of a phonograph, said motordeveloping a relatively low degree of power and being adapted to bequickly stopped by the application of a relatively lightmotion-resisting force.

The motor illustrated is mounted on a base 9, forming a part of thegeneral supporting frame. The motor includes a series of springs 10(Figs. 2 and 5) inclosed in a case 11, means including a crank shaft 12having a crank 13 for winding the springs, and a train of shafts andgearing driven by the springs, the several shafts being `journaled inbearings supported on the base as shown. Said train includes a shortshaft 14 (Figs. 1 and 3) having a small gear 15 driven by the springsthrough the intermediate gearing shown, and a larger gear 16. In a motorof this type the speed is controlled by governor and brake mechanismacting through a shaft 18 having a gear 19 meshing with the gear 16.said shaft having a brake flange 35 against which a brake shoe ispressed by the centrifugally operated means commonly employed, and shownby Figs. 1, 5 and 6.

The mechanism thus far briefly described is so well known in phonographmotors that a description of the connections between the small gear 15of the shaft 14 and the motor springs is not deemed essential. The shaft14 has another small gear 20 which has been added by me to the describedmotor mechanism. The gear 20 meshes with a larger gear 25 which isattached to the shaft 26 (Figs. 2 and 7) of a feeding member` which ashere shown is a traction roll or drum 27. over which a fillet ofmetallic leaf is passed to be taken up by a hand-operated fillet roll ora gilding die, as hereinafter described. The drum shaft 26 is journaledin bearings formed in an oscillatory or shiftable drum-supporting lever,the form of which is clearly shown by dotted lines in Fig. 1, said leverbeing composed of two members 28, 28, a neck 28h connecting saidmembers, and an extension 28 of the member Q8. The members 2S, 28 arefulcrumed at 29, 29, on upright frame members 30, 31, formed on the base9, the alined fulcrums being arranged in alinement with the shaft 14, asindicated by Fig. 7. The drum 27 is normally supported in a givenposition by the said supporting lever and by a spring 32 acting thereon,and is shiftable therefrom bv downward pressure on its upper surfacewithout disturbance of the engagement of the gears 20 and the gear beingshiftable with the drum and remaining in engagement with the gear 20during its shifting movements. The drum-supporting lever has a two-partarm formed by the portions of the membersA 28, 2S at one side of theaxis of oscillation. said members supporting the shaft 26 and drum 2".and another arm formed by the portions of said members at the oppositeside of said axis, and by the extension QSC. The drum supporting` leveris subjected to the biasing action of a spring 32 (Fig. T) which pressesdownwardly on the extension 28 of said lever and thus holds the two-partarm cf said lever and the drum supported thereby vieldingly raised, thespring 32 being snfliciently strong to support the drum in a raisedposition, so that the drum is depressible or shiftable by downwardpressure exerted upon it, the lever being swung on its fulcrum axis b ythe depression of the drum to raise its spring-pressed arm.

The frame member 31 has a slot 34 through which the shaft 26 passes.said slot permitting the shaft and roll to move vertically. The downwardmovement of the drum 2T. cause-d by the downward pressure of a filletroll on the highest portion of its lperiphery. is utilized through themeans next described to start the motor and cause the rotation of thedrum. The brake flange (Figs. l and 6) is connected with the shaft 1S torotate with it, but as here shown is movable lengthwise of the shaft bythe action of governor weights 36 carried by springs 3T. which areattachedv at their respective ends to a collar 38 fast on the shaft 1Sand a collar 39 fast on a sleeve 40 formed with the flange 35.

41 (Figs. 1. 5 and G) represents a brake shoe mounted on the swingingend of an oscillating carrier 42 which is pivoted at 43 (Fig. (3) andnormally holds the shoe 41 against one side ef the flange 35. so thatthe shoe prevents rotation of the said flange and of the shaft 18. Thebrake shoe carrier #l2 is connected by a rod 4l with one arm of a bellcrank lever 45 (Fig. 6) Which is fulcrumed at 46 and has on its otherarm an extension 45HL which extends through a slot i? in the framemember' 31 and enters a slot 48 (Fig. 7) in the spring-pressed portion'28 of the drum-supporting lever.

The described parts are so arranged that a slight depression of the drum27 will raise the lever extension 28C sufficiently to cause the bellcrank lever 45 and rod #il to swing the shoe carrier l2 away from theflange 35, and thus permit the rotation of the shaft f8. It follows,therefore. that the depression of the drum starts the motor and causesthe rotation of the drum. Upon the removal -of downward pressure fromthe drum, the spring 32 acts to raise the drum and at the same time setthe brake shoe against the fiange 35, thus stopping the motor and thedrum. Then the motor is running, the governor acts to move the fiange 35toward the brake shoe and into suflicient contact therewith to reducethe speed in it becomes more than normal. As hereinbefore stated, thegovernor is not of itself a part of my invention. In fact, the governorillustrated may be dispensed with, the flange being attached immovablyto the shaft 1S in case automatic speed regulation is not desired.

The fillet 5() of metalli." leaf. shown by broken lines in Figs. T and8. is wound with a paper strip .31 on a core (Fig. (i). the convolutionsof the fillet and strip alternating. and the whole constituting apackage roll designated by the reference p in Figs. 5 and 6. Saidpackage roll is rotatably sup ported between a fixed head 53 on theframe member 31 formed to bear on one side of the core 52. and a movablehead 5l formed to bear on the opposite side of said core, said hea-dshaving bosses 55 entering the bore of the core. The movable head 5l isattached to rods 56 which are slidable in guides in the frame member 30,and are connected by a cross bar 5T having a knob or handle A spring 59interposed bctween the frame member 3() which constitutes a fixed springabutment and the head 54. presses thelatter against the core. The fixedhead 53 andthe spring abutment portion of the fixed frame member 30 areseparated b v a relatively wide invariable space containing the movablehead. the spring, and a package roll. The heads .33 and 54 are adaptedto confine package rolls y) of various widths, the spring 59 yielding toaccommodate the width of the roll, and being of tapering or conicalhelical form, so that its convolutions nest into each other when thespring is compressed. The tension or pres sure ofi the spring on themovable head 54 is therefore automatically regulated according to thewidth of the package roll. lf the roll is relatively narrow or ofminimum wid-th, it requires less spring pressure than a wider roll. Theconical form of the spring enables the spring to be compressed with aconstantly increasing pressure and without interference of itsconvolutions with each other. until the spring assumes approximately afiat spiral form with all its convolutions in close proximity to thefixed abutment. The conical spring therefore enables a much Wider rollto be employed. Without adjustment of the abutment. than would bepossible if the spring were helical with all its convolutions of thesame diameter. The pressure of the conical spring is greater on arelatively wide roll than on a roll of minimum Width, there being nolimitation of the spring pressure by interference of the convolutions.vith each other. The movable head 5-1 is readily displaceable b v theknob or handle 58.

The drum '27 has a peripheral face 27 of yielding frictional material.such felt. leather. etc. Yhen the fillet roll (31 carried by the usualshank G3 and handle (3l (Figs. S and 9) is pressed downwardly on afillet 50 resting on the drum.y the pressure causes the rotation of thedrum as above stated. and the fillet adheres to the periphery of theroll, which is usuaily heated preparatory to use. the fillet being thusseparated from the strip 51, which is carried away by the rotation ofthe drum. The fillet is subsequently applied as usual by the roll to thesurface to be ornamented.

Fig. 6 shows a steady pin 56a attached to the fixed head 53 and passingthrough an orifice in the movable head 54 to prevent the binding orcramping of the rods 56 in their guides. A pressure roll (i6 bearingloosely on the periphery of the drum holds the strip 51 against a partof said periphery. as shown by Fig. 7, and insures the separation of thestrip from the fillet. Said pressure roll has trunnions (i7. (38. whichrotate in bearings formed by an inclined recess G9 Fig. 13) in one ofthe frame members. and b y an inclined slot (Fig. 11) in a plate 71.which is connected bv a hinge 72 with a fixed plate 73 on another framemember. The hinge is inclined. and the trunnion G8 has a groove 74 (Fig.12) engaging the plate 71 to prevent separation of the trunnion GStherefrom. as shown by Fig. 12. The pressure roll Gti is adapted to bedisplaced. as shown by Fig. 10. by a swinging movement of the plate 71.W'hen the roll is returned to its operative position, its trunnions arefree to slide in the recess 69 and slot 7() toward and from the drum'27. The `iveight of the pressure roll is therefore sufficient to holdit operatively against the strip. no springs being required. The framemembers 30 and 31 are provided With flanges 30 and 3la which overhangportions of the drum and are separated by a space vvidc enough to exposethe facing 27a. A removable cover 78. fitted at its edges on a seat 31"on the frame member 31, and in a groove 9a in the base S), forms. withsaid base and frame member. a casing inclosing the motor and thedescribed gearing. It will now be seen that the drum is started by thepressure of the fillet roll against it, and stopped when the pressure isremoved. The spring 59 and head 54 exert sufficient pressure on thepackage roll p to prevent loose rotation thereof, so that the fillet andthe paper strip stop instantly when the fillet roll is removed. and arenot fed forward by any slight continuation of the rotation of the drumdiie to its momentum after the removal of the fillet roll. hence Vthereis no waste of the fillet. The lever extension :28 is preferablyprovided with a stop stud 28d arranged to abut against a fixed .framemember above it and limit the depression of the drum by the fillet roll.The sliiftable stripand-fillet feeding member or drum 27 may be usedwith a motor or driving mechanism of any other suitable type andconstruction. the organization being such that the motor is caused tooperate by the shifting of the drum from its normal position. and isauto matically stopped by the return of the drum to its normal position.

As above stated. the casing or cover 7S. the frame base 9. and the framemember 31 entirely inclose the motor and the gearing. To preventtalnpering with the said inclosed mechanism I prefer to secure the cover78 by practically invisible or secret means, so that the cover can beremoved only by an authorized person having knowledge of said means. lhave embodied the secret cover-securing means in small pins 80 (Fig. 2),driven into registering holes in the cover 78 and in the seat 31b on theframe member 31. and similar pins 80 driven into registering holes inthe cover and in the portion of the base 9 in which the groove 9a isformed. Said pins have a close driving fit in the holes and are so smallthat their outer ends are practically invisible and can be detected onlyby a person having knowledge of their location. The pins may be ejectedinwardly to release the cover by a small punch driven against theirouter ends.

The frame member 31 is preferably formed as an integral part of the base9, and the frame member' 30 is formed independently and provided Withintegral flanges 30 and 30d (Figs. 1, 7 and 9), one located behind andthe other in front of thel drum 27, as shown by Fig. 7. said flangesabutting against the frame member 30, and being secured thereto byscrews 82 (Figs. 1 and 7). The said screws are inserted from the spaceunder the cover 78, so that they are inaccessible when the cover is inplace. The detachable frame member 30 is secured to the base by screws84 (Figs. 1 and 2) inserted in the base and engaged with slotted ears 85on the member 30, the ears being movable horizontally under the heads ofthe screws.

One of the fulcrum studs 29 is attached to the frame member 30, as shownby Fig. 2. The drum 27 and its supporting lever are installed before theframe member 30 is located and secured, said member being then movedhorizontally inward on the base until its ears engage the screws 84, andits flanges 30c and 30d abut against the frame member 31, the fulcrumstud 29 carried by the member 30 being at the same time engaged with thedrum-supporting lever. The screws 82 are then inserted to confine theframe member 30 in place, this being done before the cover 78 is appliedand secured. The fiange 80C is provided With an extension 30e (Fig. 7)projecting toward the rear side of the drum and covering the leverportionsl 28, 28@ and 28d. The flange 30d is curved at its upper portioninto close proximity to the front side of the drum, the outer side ofsaid flange forming a guide for the paper strip 51.

lt will now be seen that the detachable frame member 30 and its flan escoiiperate with the frame member 3l an the base in forming an inclosurewhich contains the drum and its shiftable supporting lever, and isinterrupted only by an opening exposing only the upper portion of theperiphery of the drum. The detachable frame member can only be removedby withdrawing the screws 8:2, and this can be done only when the cover7 8 is removed, hence the securing of the cover in the manner abovedescribed prevents access to the main portion of the drum and to thedrum-supporting means.
